Scid vs. PC requires Tcl/Tk 8.5. It should work with 8.6 , but is untested.

Most Unices should have Tcl/Tk installed by default. To verify this, look for a command named wish or wish8.5 (Wish-8.5.10 is not recommended). To enable support for extra chess pieces (such as Berlin), you may need to install TkImg. Then, installing from source:

tar -xzf scid_vs_pc-4.7.tgz
cd scid_vs_pc-4.7
configure
make install
scid
It is also possible to install Scid vs. PC into /usr, instead of the normal /usr/local. This allows for parallel installation with mainline Scid, and is done by: ./configure BINDIR=/usr/bin/ SHAREDIR=/usr/share/scid/
